I rolled my vinson and broke the back part of the speedometer, I bought the new part and I dont know how to remove the back part of the speedomer through the 1.5" hole. do the wires unplug from the back of the speedometer or do I have to unplug the wires from behind the plastic. SKU: 34111-03G00
CASE, LOWER this is the part I am replacing (from babbitts website.) thanks in advance for your help.
